为探索燃烧轻气炮点火对内弹道性能的影响，应用商业软件对其进行仿真分析，通过施加能量模拟点火源，采用计算流体力学方法对燃烧轻气炮内弹道气体流场进行数值模拟分析。计算结果表明：燃烧轻气炮点火源布置对弹底压力波动影响很大，在一定范围内合理增加点火源数量、点火能量和放电时间都可以减小弹底压力波动，但对弹丸初速影响不大。

In order to explore the impact that the ignition of combustion light gas gun on internal ballistics, the simulation was analyzed by the commercial software, the sources of ignition was simulated by the energy, the numerical simulation analysis of combustion light gas gun interior ballistics flow field was used by the method of computational fluid dynamics. The result shows that, the arrangement of the igniting sources has great impact on the projectile bore pressure oscillations and increasing the amount of the ignition sources, the time and energy of ignition within a limited range, undesirable projectile bore pressure oscillations can be controlled, but has less effect on the muzzle velocity of projectiles.
